>cd01882 BMS1 Bms1. Bms1 is an essential, evolutionarily conserved, nucleolar protein. Its depletion interferes with processing of the 35S pre-rRNA at sites A0, A1, and A2, and the formation of 40S subunits. Bms1, the putative endonuclease Rc11, and the essential U3 small nucleolar RNA form a stable subcomplex that is believed to control an early step in the formation of the 40S subumit. The C-terminal domain of Bms1 contains a GTPase-activating protein (GAP) that functions intramolecularly. It is believed that Rc11 activates Bms1 by acting as a guanine-nucleotide exchange factor (GEF) to promote GDP/GTP exchange, and that activated (GTP-bound) Bms1 delivers Rc11 to the preribosomes.
